摘要
本研究发明,在四川盆西北地区,柑桔园春季覆膜,可提高座果率,显著地减少第一次生理落果。秋季覆膜能减少25%的裂果;比对照增产10~27%;改善树冠下部果实品质,果汁中可溶性固形物、总糖含量提高,而总酸和维生素 C 变化不明显。
The results from the present experiments showed that spring mulching of Navel orange (Citrus Sincnsis Osbeck)field increased rate of fruit setting and significantly reduced the first time's physiological fruit drop;Autumn mulching reduced the fruit craking to about 25% and incrcascd the fruit yicld to 10-27%.Furthermore,the furit quality in low crown section was also improved with the increase in contents of soluble solid matter and total sugar in fruit juice.However,this method did not significantly influence the contents of total acids and vitaminn C.
